Fig. 3 is a top orV plan view of the various parts represented in said Fig. 1, with the hollow or tubular post represented in transverse section; Fig. 4 is a horizontal section, said section being taken on line 4--4 in said' Fig. 1; and Fig` 5 is a vertical section of the parts, said section being taken on line 5 5 in said Fig. 1, looking in the direction of the arrow w. Fig. 6 is a transverse vertical section of a portion of a hollow or tubular bed-post and a sectional representation of a bracket-member about to be secured to said post, said view showing within saidpost, and in elevation, a lock-plate and a key or wedge, in its raised relation with said lock-plate, all illustrating a modified construction of securing means, embodying the principles of the present invention; and Fig. 7 is a vertical section of the parts represented in said Fig. 6, said section being taken on line 7-7 in said Fig. 6, looking in the ldirection of the arrow y. Fig. 8 is a similar sectional representation of the same parts, taken on the same line in said Fig. 6, but illustrating the various parts in their assembled and locked relation; and Fig. 9 is a horizontal sectional representation, taken on line 9 9 in said Fig. 6, looking in the direction of the arrow a. i

Similar characters of reference are employed in all of theabove described views, t-o indicate corresponding parts.

Referring now to Figs. 1 to '5 inclusive of the drawings, the reference-character 1 indicates a portion of a tubular or hollow corner post ofa bedstead, that shown in the accompanying drawings being of the usual cylindrical form, but it will be evident thatthe tubing of which the post is made may be of any other desired cross-section. At the proper point where the bracket-member 2 is to be connected or joined to the said post, thel latter is provided with a suitably formed slot or opening 3. Suitably disposed within the interior of said tubular or hollow post 1 isa correspondingly shaped lock-plate, as t, sometimes' called the washer, the main body-portion of this plate in the present instance being curved, so as to provide a pair of wing-like members 5 and 6-which conform to and register with theinner surface-portions of the said post -1, substantially as illustrated in said Figs.

1, 2, 3, 4L and 5 ofthe drawings. The main body-portion of the said lock-plate 4t is likewise `provided with a slot or opening 7 of the same conformation, substantially, as that of the previously-mentioned slot or opening 3, said slot or opening 7 being adapted to be brought into registration with the said slot or opening 3, for the purposes to be presently more fully set forth. EX- tending in an upward direction from the said main body-portion of the said lockplate 4L is an extension, as 8, said extension being formed with a pair of vertically eX- tending side-lugs 9 and 10, which project forwardly in the direction toward the longitudinal central axis of the post, and are also slightly angularly arranged so as to project at their vertical marginal edges toward each other, and thereby provide a suitable guide in which is slidably retained a suitably formed key or wedge, as 11. In that surface of the said key or wedge 11 which is adjacent to the inner' surface of the post 1, and also adjacent to the inner surface-portions of the main body-portion of the lockplate 4 and its extension 8, the said key or wedge is formed with a groove or channel, as 12, said groove or channel, however, being shorter than the entire lengt-h of the key or wedge 1l, from top to bottom, as at 13 and 14, see Figs. 1 and 2 of t-he drawings, said portions 13 and 11i forming a pair of stops for limiting the sliding movements of the said key or wedge, in either direction, in the previously-mentioned guide' of the lock-plate 4, as will be presently described. n order to limit the sliding movement of said key or wedge in said guide, the extension S which forms a part of said guide is provided with an inwardly projecting stud, projection, or protuberance, as 15, which may form an integral part of said extension 8, said stud, projection, or protuberance 15 projecting into the said groove or channel 12, so as to prevent the withdrawal or displacement of the key or wedge vertically from its slidably connected relation with the lock-plate and its guide, and the side-lugs 9 and 10 of the guide also preventing any displacement of the key or wedge' 11 laterally from the guide, as will be clearly evident of an inspection ofFigs. 3 and 5 of the drawings, on account of the `correspondingly formed tapering or inmember 2 is lpreferably made with a concave or other suitably shaped end-face, as 17, adapted to register with the outer surface-portion of the post 1, and extending from said end-face 17 is a tongue-like member or extension, as 18, which is provided with a suitably lshaped key or wedge-receiving opening, as 19. The said tongue or extension 18 is adapted to be inserted into and passes through the registeringv slots or openings 3 and 7 of the post-1 and the lockplate 4;, respectively, so that the opening 19 of said tongue or extension 18 is brought directly beneath and in alinement with the said lock-pin, key, or wedge 11, when the latter is in its normally raised position indicated in Fig. 2 of the drawings. rlhe various parts hereinabove describedare caused to assume the relative positions indicated in said Fig. 2, by 'inverting or turning upf rod or other means a smart blow, the lock-'f be clearly evident.
